incomprehensibility in encoding guide
by Andrew Savchenko 07 Jan '07

07 Jan '07

Hi, all! I've mentioned some confusing example into encoding guide, in chapter "Encoding with the libavcodec codec family" in the "Examples" section: ***** mencoder dvd://1 -ofps 24000/1001 -oac copy -o Harry_Potter_2.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2400:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:autoaspect:vpass=1 -vf pullup,softskip,crop=720:352:0:62,hqdn3d=2:1:2 ***** As you can see, mbd=2 and mbcmp=3 are used together, but according to the manual: ***** mbcmp=<0-2000> Sets the comparison function for the macroblock decision, only used if mbd=0. ***** So, mbcmp option seems to be useless into this and the following (in the guide) example. Am I right?
